Week 3 Progress Report just landed and it's proof that showing up works.
Three weeks into the 6 Week Total Body Transformation and the numbers don't lie, the mirror doesn't lie, and neither does how your clothes fit right now.
Halfway through, still grinding, still getting stronger.
If you've been waiting for a reason to start your own report, this is it.
When you take keratin instead of creatine… 😂💇♂️
The gains may be questionable, but the hair game is UNDEFEATED. 🥊🔥

find your people, find your reps 🤝
Every class we run lately has been full, and that's not by accident. Right now our 6 Week Total Body Transformation groups are packed with members who started the same way. Nervous on day one, unsure they'd keep up. By week three most of them know each other's names. By week six they're showing up for each other as much as the workout. We've watched this happen enough times to know it's the room, not just the reps, that keeps people coming back. Training next to people working just as hard pulls more out of you than training alone ever did. If you've been putting off joining because you didn't want to walk in solo, that's exactly why the group works. Everyone in that room walked in the same way once.
Me: “Let’s work on your squats.”
Also me 30 minutes later: “DRAW ME LIKE ONE OF YOUR FRENCH GIRLS.” 😂🚢

let's talk about that first class you're putting off.
every single member here walked in not knowing the moves, not knowing anyone, wondering if they'd keep up.
they showed up anyway. now the workouts are awesome because the work got done, one rep at a time.
your first class is waiting on you, not the other way around. 💪
